Define raster and random scan display systems. Draw and explain how each system renders a diagonal line. [2+3]
Discuss the importance and workflow of area filling algorithms with diagrams. Explain how the flood fill algorithm works with 4-connected and 8-connected boundaries. [1+4]
Derive the homogeneous matrix for reflection about the line y = x
Describe composite transformations. Prove that the order of transformations matters by applying rotation followed by translation vs. translation followed by rotation to a point. [1+4]
Describe the purpose of window-to-viewport transformation. Derive the transformation equation and explain how aspect ratio is preserved. [1+4]
Explain the Back-Face Removal algorithm. What are its advantages and limitations? [3+2]

b. Application of Computer Graphics
c. DDA algorithm
Attempt any TWO questions
[2x10=20]Derive the general formula for the decision parameter in Bresenham's algorithm. How does integer arithmetic help avoid floating-point operations? [7+3]
Create a scenario in which the Z-buffer and Painter's algorithm produce different results. Explain why the outputs differ and illustrate how the scene would be rendered using both methods. You can include diagrams or pseudocode to support your explanation. [Hint: Start with three overlapping polygons (e.g., triangles or rectangles) in 3D space such that: One is in front of another in some regions, And behind it in other regions (i.e., their Z-depths intersect or overlap).] [5+3+2]
What is Virtual Reality (VR)? Explain the components of a typical VR system and list its uses in modern animation and simulation. [2+8]
